Unable to add a service reference to the specified OData feed

Hello,
I’m trying to build a portable class library targeting .NET, Silverlight, Windows RT and Windows Phone that acts as an OData client. I’m using Visual Studio 2012 and I have this error. Can anyone help me please to skip this ? What I did wrong ?
Thank you !
